My soul, be on thy guard; Ten thousand foes arise; The hosts of sin are pressing hard To draw thee from the skies. O watch, and fight, and pray; The battle ne'er give o'er; Renew it boldly every day, And help divine implore. Never think the victory won, Nor lay thine armor down; The work of faith will not be done, Till thou obtain the crown. Fight on, my soul, till death Shall bring thee to thy God; He'll take thee, at thy parting breath, To His divine abode.
